Xampp v - Error 2002 "Error establishing db con-tion

Postby Blabloger » 12. August 2013 16:49

Hi, all. Yesterday I set up my xampp and wordpress and started creating a blog. Everything was fine. Today - I can't login to localhost/wordpress. When I go there, it says "Error establishing a database connection". When I go to localhost/wordpress/wp-admin ,

it says:

" This either means that the username and password information in your wp-config.php file is incorrect or we can't contact the database server at localhost. This could mean your host's database server is down.

Are you sure you have the correct username and password?
Are you sure that you have typed the correct hostname?
Are you sure that the database server is running?

If you're unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.

When I go to localhost/phpmyadmin , it says:

#2002 - No connection could be made because the target machine actively refused it.

So what do I do? Any insight? I am very non-technical non-coding person so I hope there is some understandable solution. Thank you, guys, in advance!

This is what it says in the Mysql Log:
